Referring especially to Figs. 1 to 4 inclusive, 5 designates a sheet of latex having its margins 6, I and 8 reinforced as indicated at 9 (Fig. 3) by an accretion of latex integral with the sheet and terminating in a torn or feathered edge I. The fourth margin ll--of the sheet as indicated atl2 in Fig. 4 is reinforced by an accretion of latex which is somewhat similar in cross section to substantially, one half of the vertical section of a teardrop. The free edge of this reinforcement indicated at l3 terminates in a torn or feather edge. It should be noted that this sheet has two types of reinforcement, such as 9 and I2, which merge one into the other, as indicated at H in Fig. 2.\ The sheet 5 may be provided with corner openings l5 therein and if such openings are provided in the sheet, the material at the margin of each opening will be reinforced by an accretion of latex as best indicated in Fig. 6. Figs. 5, 6 and 7 disclose a latex bib or apron l6 made in accordance with the present invention. The lower portion of this bib may be generally rectangular, while its upper portion narrows down to two curved tabs 11 defining a neck opening. The ends of these tabs are provided with holes 20 to receive a button or other fastening means (not shown) which serve to hold the tabs together around the neck of the wearer. All the ma gins of this bib are reinforced by an accretion of latex l8 integral with the bib and terminating in a feather or torn edge 19. Similarly,

the bib at the holes 28 therein is reinforced by an accretion of latex 2| integral therewith and terminating in a feather or torn edge 22'.

Figs. 8, 9 and 10 disclose one style of latex cape 23 which is made-in accordance with the present invention. This cape, which is made of one piece of latex has a collar, 24 and straps or ties 25 serving to fasten the cape around the neck of the wearer. This cape also has shoulder portions 26 connected with the neck portion thereof, which shoulder portions flare outwardly to the bottom portion 21 of the cape. As herein illustrated, the cape is provided with openings 28 to receive buttons or other fastening means. All margins of the cape, including those of the collar, 24 the straps 25, the shoulder portions 26 and the other portions thereof are reinforced by a ridge of latex thereat, which ridge is preferably continuous. The reinforcing'ridge of all mar gins of the cape, except that at the bottom margin is of thecharacter indicated at 29 (Fig. 9), terminating in a torn or feather edge 38. However, the reinforcing ridge 3| at the margin of the lower portion 21 of the cape, is somewhat similar in cross section to substantially one half of the vertical section of a drop while the free edge of this ridge terminates in a torn or feather edge 32 (Fig. 10). The buttonholes 28 in the cape are each reinforced by a ridge or an accretion 33 integral with the layer of the cape which ridge may terminate in a torn or feather edge 34 or in a cut edge asv desired.

One type of latex sheet can be made on the form shown in Figs. 11 and 12. This form comprises a substantially rigid plate having panels 35 and 3B, which panels are bounded on three of their sides by the raised border 31. This border is provided with abrupt edges 38 and 39, adjacent to each of its junctions 40 and 4| with the respective panels. The bottom of this form as illustrated in Fig. 11, is not provided with a raised border, but instead terminates in an abrupt edge 42 for each panel.

In the making of latex sheets on this form,liquid latex is deposited thereon, preferably-by dipping the form while suspended from the support 43, one or more times into a liquid latex bath with a drying interval between each dip until a layer of the desired thickness is deposited on the form.

During the dipping operations the latex will tend to flow away from the abrupt edges 38, 39 and 42 to define lines of weakness thereat in the deposited layer but will tend to accrete by surface tension at the junctions 40 and 4| and will accrete in substantially the shape of one half of a drop above the edges 42. After the deposited layer is properly dried and cured the portion thereof on the border 31 is stripped or torn away as far as the lines of weakness in the layer at the abrupt edges 38 and 39. The portion 44 of the layer on each panel can then be stripped therefrom and can be torn or parted from the remainder of the layer at the lines of weakness defined by the edges 42. Three of the margins of this sheet will be reinforced by an accumulation 45 (Fig. 12) of latex integral with the sheet and having a torn or feather edge 46. The fourth margin, however, will be reinforced by a ridge of latex integral therewith, which ridge in cross section is somewhat similar to that of substantially one half of the vertical section of a drop. The free edge of this reinforcement will be in the form of a torn or feather edge as will appear hereinafter.

A formsimilar to that last described but adapted to making latex sheets with rounded corners, is illustrated in Figs. 13, 1'4 and 15. This form is likewise provided with two panels 48 and 49 partially bounded by a raised border 50 which is provided with rounded corners at its upper portion. The border 50 is provided with abrupt edges 5| and 52 and is connected with the panels at the junctions 53 and 54. This border is also provided with supports 55 by which the form can be suspended while it is being coated or dipped. Adjacent to each of the corners of the panels 48 and 49 there are provided bosses 56 which rise abruptly from the surface of the panel and terminate in abrupt edges 51. The lower edge and lower corners of the panel are not bounded by the border 5| but instead terminate in an abrupt edge 58. It should be noted that the lower ends of the border 50 extend to a point below the center of curvature of the rounded lower corners of the panel.

In making sheeting on this form the form is coated or dipped as 'previously described, as a result of which the latex sheet 5, which is shown in Figs. 1 to 4 inclusive, will be formed. The

border 50 generates a reinforcement 9, at three of the margins'of the sheet, which reinforcement terminates in a torn or feather edge Hi. However, the abrupt lower edge 58 of the form defines the reinforcement l2 which terminates in a torn or feather edge l3. It will be understood that the reinforcement l2 merges with the reinforcement 9 as indicated at l4 in Figs. 2 and 16. The bosses 56 on the panel generate holes 15 in the sheet, the material at the margin of each hole being reinforced as indicated at 60, which reinforcement terminates in a torn or feather edge 6 I.

When the invention is utilized in making a shower bath curtain 63, the form shown in Figs. 19 and 20 is employed. This form difiers from that just described in'that its dimensions are different and a single row of bosses 62 is provided along the upper margin of the panels.

In making the bib or apron shown in Fig. 5, a form illustrated in Figs. 22, 23, and 24 is provided. This form which is adapted for the making of a bib or apron on each side thereof simultaneously, is provided with two depressed panels 64 and 65, which panels are bounded by a continuous border 66. .This border at its upper portion converges toward the top where it connects with a circular boss .61. This boss which is of such size as to define a neck opening, also serves to define neck bands or straps I1 (Fig. 5). The border 65, as well as the boss 61, rise abruptly from the junctions 68 with the panel, while the border and the bosses terminate in abrupt edges 69. Those portions of the form where it is desired to provide holes for buttons or other fas teners in the resulting bib, are provided with bosses 10 projecting abruptly from the form and terminating in abrupt edges.

A continuous latex strip 84 (Fig 28) with reinforced margins 85 can be made in accordance with this invention. In the making of such a latex strip an endless flexible belt (Fig.27) such as 80 is provided, a fragment only of which is herein disclosed. This belt as herein shown is provided at each edge with a raised border 8|, which projects abruptly from the face of the belt and terminates in abrupt edges 82. It will be noted that the belt is so shaped that a continuous strip may be formed oneach surface thereof. While the belt 8,100,578 can be supported and driven in any convenient of the belt has its margin reinforced by a ridge '5 which terminates in a torn orcut edge 86.

The cape illustrated in Fig. 8 can be made on a form 90 illustrated in Figs. 29, 30, and 31. This form which is adapted to making simultaneously a cape on each surface thereof, is provided with the panels 9| and 92. These panels with the exception of the lower portion thereof are-bounded by a border 93 which rises abruptly from its junction with the panel and which terminates in an abrupt edge 94. The lower corners and lower portions of the panels, however, are not provided with a border, but instead terminate in abrupt edges 95 with rounded corners identical with those shown in Figs. 13 and 19. The panels are provided with raised bosses 96 on those portions thereof where it is desired to generate an opening in the resulting cape. It will be understood that the border 93 and its related panel generates the reinforcement 29 for the margin of the cape, which reinforcement terminates in a torn or feather edge 30. However, the abrupt edge 95 of the form generates the type of reinforcement" indicated at 3| which reinforcement terminates in a torn or feather edge 32. The bosses 96; however, generate the holes 28 in the cape, which holes are reinforced as indicated at "with the reinforcement terminating in a torn or feather edge 3. I I 7 In making late capes on this-form, a layer of latex is deposited thereon such' as by dipping the form into a latex bath in the manner set forth above. Thereafter the excess portion of the latex layer as far as the abrupt edges 94 and 95 is separated from the resulting capes by cutting, stamping, clicking or tearing. The portions of the layer coveringthe faces of the bosses 9 are likewise removed by cutting or tearing to provide the buttonholes 2B in the capes.

The term "accretion" as herein used means a reinforcement for a margin of the garment, which reinforcement is built up naturally by a gradual increase or external addition of the liquid latex due to the cohesion thereof and .without the use of mechanical pressure as in the case of molding rubber.

While several embodiments of the invention have been disclosed, it will be understood that this invention is capable of still further modificationsand that this disclosure is intended to cover any variations, uses or adaptations of the invention falling within the scope of the appended claims.
